mine are being handled by purolator. in fact as i type they're probably on a truck or train approaching Belleville! in about 12 hours i'm hopping to hear my doorbell go ding dong! will i be happy i spent 2 thousand dollars? will i easily be able to find the defects on my outlet speakers? i'm really hoping these speakers will be a sound revelation the way my Shure earphones were when i first heard them.

What does this button do?
